For just $3.75 Has your little one outgrown their teething necklace? Instead of buying a new necklace, you can buy as little as .75" to as long as 3.5". Simply choose the length, clasp, and color/style that you need! This will come as a traditional twist clasp extender unless you choose the option of safety tension clasp. **Remember that the safety tension clasp will only work on jewelry that already have a safety tension clasp and the screw clasp will only work on jewelry that already has a screw clasp. So you will want to order the extender with the kind of clasp that you already have UNLESS you choose a safety clasp conversion. This gives you the option to turn your traditional twist clasp into a necklace with a safety tension clasp, but only by adding 1.5" or more because the 2 clasps together total 1.5". Picture 2 is of a 1.5" super calming girl and a 1" hazelwood extender. Pictures 3 and 4 are of a 3.5" hazelwood only extension. It is an easy way to wear hazelwood without having to replace the whole necklace when it becomes saturated. Simply replace the extension! (it is a picture of my very own necklace!)
